Wouldn't it be refreshing if OpenAI and Anthropic were this open, and spelled out how they were using their own models during development and rollout?!

All I can recall reading from OpenAI about what they have actually done in the name of "RSI" is using one of their models to help automate the training process.

OpenAI did recently get into how they had been building their own hardware and doing RSI with it.

That's more than Anthropic has done though.
